The First Edition of The Sun from Space, completed in 1999, focused on
the early accomplishments of three solar spacecraft, SOHO, Ulysses, and
Yohkoh, primarily during a minimum in the Sun's 11-year cycle of
magnetic activity. The comp- hensive Second Edition includes the main
ndings of these three spacecraft over an entire activity cycle,
including two minima and a maximum, and discusses the signi cant results
of six more solar missions. Four of these, the Hinode, RHESSI, STEREO,
and TRACE missions were launched after the First Edition was either
nished or nearly so, and the other two, the ACE and Wind spacecraft,
extend our investigations from the Sun to its varying input to the
Earth. The Second Edition does not contain simple updates or cosmetic
patch ups to the material in the First Edition. It instead contains the
relevant discoveries of the past decade, integrated into chapters
completely rewritten for the purpose. This provides a fresh perspective
to the major topics of solar enquiry, written in an enjoyable, easily
understood text accessible to all readers, from the interested layperson
to the student or professional.
